Reaction rate constant of phosphate esters with hydroxyl radicals investigated using fluorescence probe method

Fushe yanjiu yu fushe gongyi xuebao
The strong fluorescence of 7-hydroxycoumarin yielded by the reaction of coumarin with hydroxyl radicals (•OH) was used as a fluorescent probe to determine the yield of 7-hydroxycoumarin aqueous solutions with different concentrations of TBP and TiAP ...

Macrokinetics of the deterioration of cement-based grouting material for predicting its service life under acid rain attack

Heritage Science, 2023
Cement-based grouting material is widely used to reinforce the unsafe rock and control seepage of rock-carved relics although it is considered inappropriate in protection of ancient sites.

Flame Enhancement and Quenching in Fluid Flows [PDF]

, 2002
We perform direct numerical simulations (DNS) of an advected scalar field which diffuses and reacts according to a nonlinear reaction law. The objective is to study how the bulk burning rate of the reaction is affected by an imposed flow.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Semiclassical reaction rate constant of non-adiabatic system by means of initial value representation

AIP Advances
We applied the semiclassical initial value representation (SC-IVR) method with the classical electron analog to deal with electronically non-adiabatic reactive barriers and calculated the thermal reaction rate constant.

Kinetics of the HO_2 + BrO reaction over the temperature range 233–348 K [PDF]

, 1997
The reaction BrO + HO_2 → products is the rate-limiting step in a key catalytic ozone destruction cycle in the lower stratosphere. In this study a discharge-flow reactor coupled with molecular beam mass spectrometry has been used to study the BrO + HO_2 ...

Combining antibody conjugates with cytotoxic and immune‐stimulating payloads maximizes anti‐cancer activity

Molecular Oncology, EarlyView.
Methods to improve antibody–drug conjugate (ADC) treatment durability in cancer therapy are needed. We utilized ADCs and immune‐stimulating antibody conjugates (ISACs), which are made from two non‐competitive antibodies, to enhance the entry of toxic payloads into cancer cells and deliver immunostimulatory agents into immune cells.

Impact of ultrasonic dispersion on the photocatalytic activity of titania aggregates

Beilstein Journal of Nanotechnology, 2015
The effectiveness of photocatalytic materials increases with the specific surface area, thus nanoscale photocatalyst particles are preferred. However, such nanomaterials are frequently found in an aggregated state, which may reduce the photocatalytic ...
